Specication of Letters Patent. Application led November 3, 1913.

`Patenten May 19, 1914', sei-iai no. wasn.

To all whom it may concern Be it known that I, FRANKLIN E. AnND'r, a citizen of the United States, residing Aat Galion, in the county of Crawford and State of Ohio, have invented certain new and useful Improvements in Culverts, of which the following is a specification.

This invention relates generally to pipes and mains and more particularly to sheet metal culvert pipes for light culvert and drain use, the same being preferably corrugated.

The invention has for 'its primary object a simple, strong, li ht, cheap, elicient and all-around servioea le corrugated culvert pipe formed out of semi-cylindrical sections of predetermined length capable of being shipped in nesting relation with each other, whereby freight charges are materially reduced, the parts being so constructed and arranged that they may be easily assembled at the point of installation so as to make a secure joint at the side seams and form a complete cylindrical pi e section without the necessity of special too s or of skilled labor. And the invention also aims to generally improve devices of this class so as to render' them more useful and commercially desirable.

With these and other objects in view, as will more fully appear as the description proceeds, the invention consists in certain constructions, combinations and arrangements of the parts that I shall hereinafter more fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a side elevation of a culvert pipe embodyin the improvements of my invention, one o the clamps being omitted to show the erforations and recesses in the sections. ig. 2 is a fragmentary transverse sectional view thereof, and, Fig. 3 is a perspective view of one of the clamps detached.

Correspondingand like parts are referred to in the following description and designated in the accompanying drawing by like reference characters.

Referring to the drawing, the numeral 1 designates one of the semi-cylindrical corrugat'ed pipe sections or parts preferably formed from sterling galvanized metal ing sections 1 when the parts are assembled to form a complete cylindrical culvertpipe. Each .clamp is preferably formed at its' middle with a boss, as shown, and an opening 6 extends through the boss from one side of the clamp to the other and is designed 'to receive the shank of a bolt 7, .the head of the bolt being preferably disposed innermost and the outer threaded end receivin a binding mit 8 which screws up against t side of the clamp 4. The shank of the bolt 7' is also received or accommodated in the registering and overlapping edge recesses 3, which permit the overlapping edgesof the assemb ed sections 1 to draw in one upon the lugs 5 in the perforations 2, while at the same time, the overlapping edgesof the sections will bc tightly pressed one against the other.

From the foregoing description in connection with the accompanying drawing, it will be understood that in the assembling of the parts, the semi-cylindrical sections'will be fitted one u on t e other to form the complete -cylin rical structureA with the side edges 0f the sections overlapping, and the clam s will then be placed in position, as clear y illustrated in the drawin and the bolts passed outwardly the nuts then applied, being capable of being quic ly and expeditious y and without the necessity of special tools or skilled labor. As these sections are usually made in units of about, say, two feet in length, it will be seen that no trouble at all will e experienced in passing the bolts outwardly from theinside with the heads of the bolts abutting against the inner wall of the culvert pi While the accompanyin drawing illustrates what I believe to be t e preferred embodiment of my invention, it is to be undere outer other when the nut is tightened up with the i from the inside and 1 I( this entire operation performed very' stood that the to, as various construction,

scope of the inventiun, as detined in the ap )ended elaiins.

lVhet: l claim is:-d

1. A culvert pipe lnade up nl a number of sections overlapping at their side edges and formed in said overlapping edges with reg istering recesses and near said edges in eireumterential alinelnentI with said recesses, with perfuratiens, clamps formed with lugs adapted t0 fit in said perferations with the clamps extending across the overlapping edges of the sections, the clamps being further formed with openings adapted to register with the recesses, and bolts receivable in said overlapping recesses and said openings and adapted to be secured to the clamps.

Q. A culvert, pipe made up of a, number o sections overlapping at then' side edges and formed in said edges with circumferentially elongated recesses and near said edges with perforations in circumferential alinement with said recesses, clamps adapted t0 extend across the overlapping edges and Jformed with lugs fitting 1n said perferations, and withdrawable means arranged to draw the arrangement and preportiens"k of the parts without departinu from the Clamps inwardl tow-.1rd thc mcrlappingr Ledges. said inc-ans llcinglr rcccirahle in the edge recesses.

A culvert pipt` made up nf a nlnnher nl', sections overlapping al their side edges and foi-ined in said edges with elungated recesses and ucar said edges with perl'nratiens in circuin'crential alinenient; i with the recesses. clamping bars adapted te extend acrnssl ther m-'erlappingr side edges of the seetiuns and nrnicd at their endsl with inwardlyv extending lugs receivable in said perforatinns and with middle openings adapted tu register with the registering recesses in the overlapping edges, and belts insertible threngh .said recesses and the upenings in the clamping bars, the heads of the bolts being disposed inwardly and abutting againstJ the inner wall ef the culvert pipe and the Outer ends of the belts being provided Wit-h nuts adapted to screw up against,

the outer sides of the elaniplng bars. n
